Chicago - Jurassic fever struck Chicago yesterday as the Field Museum unveiled the most complete Tyrannosaurus rex fossil ever found - a 12.5m monster that lumbered the Great Plains 67 million years ago.
The creature - which cost $8.4 million in an auction - had provided some scientific surprises. One is the presence of a wishbone, the first ever found in a T-rex and additional proof for those who believe dinosaurs are related to birds.
